Poetry appears as a phenomenon of freedom

The poetic image is an emergence from language, it is always a little above the language of signification. By living the poems we read, we have then the salutary experience of emerging. This, no doubt, is emerging at short range. But these acts of emergence are repeated; poetry puts language in a state of emergence, in which life becomes manifest through its vivacity. These linguistic impulses, which stand out from the ordinary rank of pragmatic language, are miniatures of the vital impulse. A micro-Bergsonism that abandoned the thesis of language-as-instrument in favor of the thesis of language-as-reality would find in poetry numerous documents on the intense life of language.

Thus, along with considerations on the life of words, as it appears in the evolution of language across the centuries, the poetic image, assa a mathematician would say, presents us with a sort of differential of this evolution. A great verse can have a great influence on the soul of a language. It awakens images that had been effaced, at the same time that it confirms the unforeseeable nature of speec. And if we render speech unforeseeable, is this not an apprenticeship of freedom? What delight the poetic imagination takes in making game of censors! Time was when the poetic arts codified the licenses to be permitted. Contemporary poetry, however, has introduced fredom in the very body of the language. As a result, poetry appears as a phenomenon of freedom.
